The James River Rundown began as a two-day 100-mile paddling race in 2014 with all proceeds supporting the James River Association, a member-supported nonprofit river conservation organization. 100-mile, 40-mile,and 20-mile races are offered this year. All three races will share a finish line and a much needed after party with music, refreshments, and food at American Legion Post 354 in Chesterfield County.
